=== 1. :check 는 archive-hygiene 게이트에서 실패한다 (소스와 무관) ===
$ ./gradlew :adapter:outbound:httpclient:check  → BUILD FAILED
원인: build/libs 에 이전 리비전 JAR 이 남아 있음
$ ls src/adapter/outbound/httpclient/build/libs
httpclient-0.0.1+0137263441f6.jar
httpclient-0.0.1+a24ece9cf797.jar
httpclient-0.0.1+e98b56eb03ec.jar
exit=0

게이트 정의: src/gradle/archive-hygiene.gradle — 저장소가 remedy 태스크 cleanStaleTraceableJars 를 제공한다.
이 분석은 사용자 워크스페이스의 빌드 산출물을 삭제하지 않았다.

=== 2. 다섯 lane 개별 실행 ===
$ ./gradlew :adapter:outbound:httpclient:test :…:httpClientStableContractTest :…:httpClientSecurityTest :…:httpClientBlockHoundTest :…:spring62ApiSurfaceScan
GRADLE_EXIT=1 — :test 에서 283 tests completed, 3 failed

=== 3. JUnit 집계 ===
test: classes=61 tests=283 failures=3 errors=0 skipped=0
httpClientStableContractTest: classes=7 tests=24 failures=0 errors=0 skipped=0
httpClientSecurityTest: classes=2 tests=9 failures=0 errors=0 skipped=0
httpClientBlockHoundTest: classes=1 tests=3 failures=0 errors=0 skipped=0
spring62ApiSurfaceScan: classes=1 tests=6 failures=0 errors=0 skipped=0

=== 4. 실패 3건의 정확한 내용 ===
anUntrustedAuthorityIsAPermanentTlsFailure() -> org.opentest4j.AssertionFailedError:  expected: TLS_HANDSHAKE  but was: CONNECT
anExpiredCertificateIsAPermanentTlsFailure() -> org.opentest4j.AssertionFailedError:  expected: TLS_HANDSHAKE  but was: CONNECT
aHostnameMismatchIsAPermanentTlsFailure() -> org.opentest4j.AssertionFailedError:  expected: TLS_HANDSHAKE  but was: CONNECT

=== 5. 원인: 원인 사슬을 바깥부터 훑고 CONNECT 분기가 TLS 분기보다 앞에 있다 ===
